Answer:
1 ohm
Explanation:
First of all, the equivalent resistance for two resistors (r₁ and r₂) in parallel is given by:
1 / Eq = (1 / r₁) + (1 / r₂)
The equivalent resistance for resistance for two resistors (r₁ and r₂) in series is given by:
Eq = r₁ + r₂
Hence as we can see from the circuit diagram, 2Ω // 2Ω, and 2Ω // 2Ω, hence:
1/E₁ = 1/2 + 1/2
1/E₁ = 1
E₁ = 1Ω
1/E₂ = 1/2 + 1/2
1/E₂ = 1
E₂ = 1Ω
This then leads to E₁ being in series with E₂, hence the equivalent resistance (E₃) of E₁ and E₂ is:
E₃ = E₁ + E₂ = 1 + 1 = 2Ω
The equivalent resistance (Eq) across AB is the parallel combination of E₃ and the 2Ω resistor, therefore:
1/Eq = 1/E₃ + 1/2
1/Eq = 1/2 + 1/2
1/Eq = 1
Eq = 1Ω

Answer:
Power generate by generator = 265 W (Approx.)
Explanation:
Given:
Mass of student = 62 kg
Height of stairs = 3.4 meter
Time taken = 7 second
Find:
Power generate by generator
Computation:
Power = Force x [Distance / Time]
Power = [Mass x gravitational acceleration] x [Distance / Time]
Power = [62 x 9.8][3.4/7]
Power = [607.6][3.4/7]
Power = 265.12
Power generate by generator = 265.12
Power generate by generator = 265 W (Approx.)
